JS8Call <-> SparkSDR, CAT not working

[Rick Spanbauer]

Hi Folks, I'm giving JS8Call a test drive on my M4 Mac with SparkSDR.  Versions:

Hermes Lite 2

SparkSDR.app.2_0_991

JS8Call-improved v2.4.0

using the vb-audio loopback software

I have one transceiver configured in SparkSDR, with CAT enabled, and on

port 51111.  In JS8Call, Radio tab, I have the Network Server set to

127.0.0.1:51111.  When I run a tcpdump -I lo0 port 51111, I can see packets

go back & forth.  If I turn off CAT in the SparkSDR software, JS8call pops

a rig error window immediately.  The rig is set to hamlib as the docs specify.

Test CAT only intermittently changes to green as one would expect.  Test PTT

doesn't kick the SparkSDR into transmit mode.

The JS8call receiver is picking up activity.  Oddly, the CAT indicator on the main

display is Green, enough though the transmitter won't .. transmit.

Does anyone have a similar combo working?  If so, did the software basically just

work, or were they some tricks to get it running smoothly?

I did try rolling back to an earlier version of SparkSDR (2.0.33).

Note that SparkSDR is working just fine with wsjtx on the same machine.
